Rather than rely on a public Wi-Fi hotspot, which may have AP Isolation turned on or otherwise not allow data to transfer between devices inside its firewall, or through a Bluetooth connection which can be much slower than Wi-Fi, you may create a temporary Wi-Fi network directly between your Mac or PC and iPad. This device-to-device Wi-Fi network, called Ad-Hoc (or sometimes computer-to-computer or peer-to-peer) may be created in both Mac and Windows operating systems. The configuration instructions are different depending on your operating system, and outlined below in two parts.
Part 1a: Creating an Ad Hoc Network in Mac OS X
If the Wi-Fi Status Icon isn’t shown in your OS X Menu Bar, choose Apple Menu -> System Preferences, and then click Network:
Click “Wi-Fi” and select the “Show Wi-Fi status in menu bar” checkbox:
Choose “Create Network” from the Wi-Fi status icon in OS X’s Menu Bar:
Now, give the new Ad Hoc Wi-Fi network a name, and select a channel from the pop-up menu. In our example, we typed LightroomMac as the network name, and used the default channel of 11:
Note: Ad Hoc networks are not compatible with the stronger encryption WPA or WPA2 protected networks - for this reason, and the relative ease of cracking WEP-encrypted networks, we suggest not using encryption for Ad Hoc Networks, as it doesn’t provide any substantive protection.
After you create an Ad Hoc Wi-Fi network, the Wi-Fi status icon in your Mac’s menu bar will change to the Ad Hoc mode icon.
Now, skip ahead to the Connecting iPad to an Ad Hoc Wi-Fi Network section.
Part 1b: Creating an Ad Hoc Network in Windows
Part 2: Connecting iPad to an Ad Hoc Wi-Fi Network
Go to the Settings app on your iPad:
Tap on Wi-Fi in the left-hand column, ensure Wi-Fi is turned On, then select the Ad Hoc Network created by your Mac or PC, listed under Devices.
Once you tap on the Ad Hoc network created by your Mac or PC, you should be able to sync Photosmith for iPad with Lightroom as you normally would.
